Before we can convert volt-amps to amps we need to understand a little bit more about what these measurements are. A volt-ampere (VA) is a measure of the apparent electrical power while an amp (A) is a measure of electrical current.

Single phase VA to amps calculation formula

The current I in amps is equal to the apparent power S in volt-amps, divided by the voltage V in volts:

I_(A) = S_(VA) / V_(V)

3 phase kVA to amps calculation formula

The current I in amps is equal to 1000 times the apparent power S in volt-amps, divided by the square root of 3 times the line to line voltage V_L-L in volts:

I_(A) = S_(VA) / (√3 × V_L-L(V) ) = S_(VA) / (3 × V_L-N(V) )
